Answer:

106

Step-by-step explanation:

a=74

c=?

180-74=106

Answer:  106 degrees

============================================================

Explanation:

As the hint states at the top, supplementary angles add to 180 degrees

If we glued the angles together, then we'd form a straight line.

angleA+angleC = 180

74+C = 180

C = 180-74

C = 106 degrees
